Reading Microsoft Excel spreadsheets in Java

Is it possible to read a Microsoft Excel spreadsheet in Java? If so, how does one do it?

There exist the JDBC-ODBC bridge driver which enables interaction with Excel files using JDBC, but you're restricted to only one platform (Microsoft Windows), only one (free) driver which is full of bugs and inefficiency (the JDBC-ODBC bridge driver), only one worksheet (the first of the spreadsheet) and only the retrieval of the pure data (no functions, formats, graphs, images, etc).
Bad idea after all.
If the sole purpose is to have an embedded database, rather consider JavaDB, Derby or Hypersonic instead of Excel.

How to view excel spreadsheet in java

Hello
Is there a way to open an excel spreadsheet in java? I don't mean reading and writing from an excel file, but instead embedding excel in java. For example instead of launching excel using the Desktop class and opening a new excel window, Java would open an instance of excel and add it to Jframe or Jpanel. Sort of like what Eclipse does when you Open a file with In_Place Editor. Google returns results on how to use some windows dll file and using active x control or whatnot.. Was wondering if there is a better and simpler way..
Thank you.

My first try with "embed excel in Java" returned as the first link a page from a company named JIntegra for which this seems to be their main business. Here's the link I found, just for information:

Extracting data from Microsoft Excel spreadsheet

Hi,
I am currently developing an application that requires to extract data from Microsoft Excel spreadsheet. Is that possible to archieve it?
If it is possible,your precious guidience will be much appreciated.
Thank you.

There are several approaches.
1) Export the data from the Excell in "CSV" format, which is simple enough to read as an ordinary text file.
2) Use the open source POI package, which reads and writes XSL files (amongst other popular formats).
3) Use the JDBC/ODBC bridge and the Windows ODBC driver which allows and Excell file to be treated as a database. (More details in above reference).
4) Use another open source package to connect to Excell via the COM+ interface, and access data therein.
Personally I favour the POI package.

How to Format Microsoft Excel spreadsheet generated using RFC

Hi Portal Experts,
Currently, I've managed to generate a Microsoft Excel spreadsheet using a customized RFC. The spreadsheet was initiated when submitting data from Portal.
But, the data generated in Microsoft Excel was not formatted according to my specification. How could I format the data, alignment and to inset image file in Microsoft Excel automatically when this RFC is being called?
Cheers.
Bryan

Hi Jithu,
If you tried to write the the template the proper (textual) datatypes and the column is and it does not work then
I only can suggest to write a macro that does the Text Column conversion and have the macro triggered from within the package perhaps better off using a separate process (e.g. a console app that is done using Office interop libraries) as doing it right in
the package is quite laborious.

C# Script to open and read an Excel spreadsheet with multiple worksheets

Can someone provide me the C# syntax and Edit Script to open an Excel spreadsheet with multiple worksheets and then using the data to create and output a .csv file? The multiple worksheets contain different data elements that I'll need to parse out and then
store as a .csv file that will then be read to pump data into our SQL Server Database.
Thanks for your review and am hopeful for a reply.

I think this code originally came from Joel, who comes here quite a bit. I'm not a C# expert, like Joe is, but I think this is pretty close to what you want.

Do you need help getting everything into a CSV, or can you take it from here???
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

Servers don't access the file systems of client machines.

All Microsoft applications(Excel, Word, Powerpoint) will not open. Message reads: "Microsoft Excel quit unexpextedly". Attempts to relaunch fail.

Microsoft applications will not open. Scree message reads: The application of Microsoft Excel(also same for powerpoint and word) quit unexpectedly. They did not quit they just don't open. Attempts to relaunch fail. This happened several times before but relaunches were successful. How do I reopen?

Buy version 2011 of MS Office.
Or you can download OpenOffice, LibreOffice or NeoOffice, which all come very close to working with MS files just like MS Office does.
Or iWord, I have heard, you can purchase.

I switch to csv as you mentioned it's easier.HEEEEEEEEEEEEEEEEEEEEEEELLLPAnswer the following list where you have spent 30-40 hours a week for each peiod doing the following:
Have you been programming in java at least a year?
Have you programmed in another OO language such as C++, Smalltalk for at least a year?
Have you programmed in another procedural language such as Basic for at least two years?
Have you programmed in SQL (Oracle PSQL, MS SQL Server TSQL) for at least six months?
Have you used a database reports generator such as Crystal Reports for at least a year? (Again note that this means 30-40 hours a week.)
If the answer to all of the above is no then you are not going to accomplish any of the things that you have stated here "quckly".
If you answered yes to some of the above then that gives us a starting point. So post your answers.

you don't need to write ugly text file parsing codeParsing code isn't 'ugly' unless you don't know how to write it.I agree. However, in general people write lot of conditional statements and loops to handle different scenarios while processing text files.
what if the delimiter itself is part of your data?The answer to that is already defined in the CSV format.Agreed, but the complications (I gave one example only) you need to tackle unless you copy or use some existing CSV file parsing code. Moreover, why to bother so much when you have a free and open source sophisticated API.
I can think of a few reasons. At least with POI (not sure WRT to JExcel, but my guess is that this is still a valid statement), you have to build the document in memory. It is only written once all the various components have been specified in memory and then flushed to a stream. Therefore, large workbooks are problematic.
With a CSV, I have no such issues whatsoever. I can process row-by-row with very little memory overhead. For an application, say, generating reports via Excel, this can be a nontrivial issue.
I never said the approach: excel >> CSV >> process text is not a good option.

How to read an excel sheet in java

hi all!
i want to read data from an excel sheet.could U plz send me the code from scratch.
thanks in advance

Look for jxl.jar (http://www.andykhan.com/jexcelapi/) or jexcel. Worked fine for me. And as for the code: see the example programs and documentation....
Sample:
     private ArrayList procesExcelFile(File file){
          logger.info("Processing XSL file ("+file.getAbsolutePath()+")");
          ArrayList result = new ArrayList();
          Hashtable xlsRow = null;
          int row;
          try{
               // Open sheet
               WorkbookSettings wbs = new WorkbookSettings();
               wbs.setInitialFileSize( (int) file.length());
               Workbook workbook = Workbook.getWorkbook(file,wbs);
               Sheet sheet = workbook.getSheet(0);
               // Init XML tags on 1st header
               this.readTagLine(sheet.getRow(0));
               // Read sheet row by row, skip first & empty rows
               for(row = 1; row < sheet.getRows(); row++){
                    xlsRow = this.convertRowToTable(sheet.getRow(row));
                    if(!xlsRow.isEmpty()){
                         result.add(xlsRow);
               logger.info("Processed XSL file, " + result.size() + " rows found (excl. header)");
          catch(IOException ioe){
               logger.error("Error reading XLS file", ioe);
               succes = "false";
          catch(BiffException be){
               logger.error("Could not get workbook from XLS file", be);
               succes = "false";
          catch(OutOfMemoryError oome){
               logger.fatal("Not enough memory for processing XLS file", oome);
               succes = "false";
          return result;
     }now gimme them Duke Dollars ;)
